How to cyclically rotate the elements of int array left N times in Python

Answer 1

def rotate_array_left_one_time(lst):
    first = lst[0]
    lst_size = len(lst)
   
    for i in range(lst_size - 1):      
        lst[i] = lst[i + 1];
          
    lst[lst_size - 1] = first;
        

lst = [4, 7, 2, 9, 3]
lst_size = len(lst)
   
n_times = 3
   
for i in range(n_times): 
    rotate_array_left_one_time(lst)
       
print(' '. join(str(i) for i in lst))
